BERMAD Operation Manual
Flush Mode
Defines how the flushing cycles are triggered. Select one of the following options:
• OFF – no flushing occurs.
• Time – flushing cycles are repeated in a defined interval or are triggered by the DP signal - whichever happens
first. No matter how the flushing cycle started, the interval to the next cycle starts counting down at the end of
the current flushing cycle. Select one of the following time intervals:
»5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 minutes
»2, 3, 4, 5, 6, 8, 12, 18, 24, 72, 120 hours
• DP – flushing is triggered by DP only.
NOTE: When in Flush Mode, press and hold the and keys to display the time remaining until the next cycle -
alternately hours and minutes.
Accumulations
• The unit accumulates and displays the number of flushing cycles initiated by DP, by time, or by manual
activation.
• At each of the accumulation fields, the or keys can be used to change the accumulation value.
4. Configuration Process
To begin the configuration process, press and hold the ENTER key for 3 seconds.
The unit detects how many plug-in boards (each with 2 outputs) are used in the system.
Configuration Process Definitions
During the configuration process the following features are defined:
• Main Valve (sustaining valve) – Yes/ No. When the answer is Yes the Pre Dwell delay between the Main Valve
opening and the Station No. 1 opening can be defined. The selectable delay steps are:
»5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55 sec
»1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 min
• Dwell time – the delay between stations; can be set to 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, or 60 sec.
• DP delay – the delay during which the DP sensor reading is expected to remain stable before reaction; 5, 10, 15,
20, 25, 30, 35, 40, 45, 50, 55, 60 sec.
• Looping limit – the number of consecutive flushing cycles triggered by the DP sensor before an endless looping
problem is indicated. The options are: 1-10 or select no to ignore the looping problem.
• Alarm - Yes/No – allocating one output for alarm activation.
• Delay Valve – Yes/No; allocating an output for Delay Valve activation.
• View Outputs – a special mode that enables scrolling through all outputs to see how each output was allocated.
Use the key to alternate between no and yes and confirm by pressing the key. Continue to press the
key to scroll through the list. At the bottom left corner the ordinal number of the output is displayed and
